+echo "🔐 HMAC File Server 3.3.0 - Enhanced Security Analysis"
+echo "======================================================"
+
+echo ""
+echo "📋 Current Security Model Analysis:"
+echo "• Session-based authentication with 72-hour persistence"
+echo "• Token refresh mechanism (up to 10 refreshes)"
+echo "• Network change detection and logging"
+echo "• Standby recovery with 24-hour grace extension"
+
+echo ""
+echo "🔒 Security Enhancement Proposal:"
+echo "=================================="
+
+echo ""
+echo "1. SMART RE-AUTHENTICATION TRIGGERS:"
+echo "   ✓ Network IP change detected (5G ↔ WiFi)"
+echo "   ✓ Device standby > 30 minutes"
+echo "   ✓ Multiple failed authentication attempts"
+echo "   ✓ Suspicious user agent changes"
+echo "   ✓ Geographic location changes (if available)"
+
+echo ""
+echo "2. PROGRESSIVE SECURITY LEVELS:"
+echo "   • Level 1: Standard session refresh (current)"
+echo "   • Level 2: Challenge-response with existing secret"
+echo "   • Level 3: Full re-authentication required"
+
+echo ""
+echo "3. IMPLEMENTATION STRATEGY:"
+echo "   • HTTP 401 Unauthorized with WWW-Authenticate header"
+echo "   • XEP-0363 compliant re-authentication flow"
+echo "   • Client-side automatic secret renewal"
+echo "   • Transparent user experience for trusted scenarios"
+
+echo ""
+echo "4. SECURITY BENEFITS:"
+echo "   • Prevents token hijacking during network transitions"
+echo "   • Mitigates risks from device theft/loss"
+echo "   • Ensures fresh credentials after standby"
+echo "   • Maintains zero-configuration user experience"
+
+echo ""
+echo "🎯 RECOMMENDED IMPLEMENTATION:"
+echo "• Network change: Challenge-response (Level 2)"
+echo "• Standby > 30min: Full re-auth (Level 3)"
+echo "• Same network: Standard refresh (Level 1)"
